I'm pretty lucky in that I don't have too much trouble sleeping. Occasionally I will try to go to bed and I am not tired at all and will end up watching TV. Usually within an hour I am asleep though. I haven't had much of a problem waking up in the middle of the night and not getting back to sleep, this only happens to me when I have to get up earlier than normal and I get up maybe 90 minutes before my alarm is supposed to go off and I freak out a bit that I have to get up in only 90 minutes, etc.
